A TTOR/VEYS JOHN PHILIP MGEVOY, OF SOUR LAKE, TEXAS.
VALVE STRUCTURE FOR OIL-WELLS.
Specification of Letters Patent.
Patented Sept. 21, 1920.
Application filed September 19, 1919. Serial 110. 324,908.
T 0 all whom it may concern:
Be it known that I, JOHN PHILIP Mo EvoY, a citizen of the United States, residing at Sour Lake, in the county of Hardin and State of Texas, have invented new and useful Improvements in Valve Structures for Oil-Tells, of which the following is a specification.
My invention relates to improvements in vzlilve structures for use in oil wells or the li (e. 7
An important object of the invention is to improve the valve element of such structures, with a view of increasing the efiiciency and durability of the device.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification, the figure is a central vertical longitudinal view 'through a device embodying my invention.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral l designates a barrel or tubular body portion of the valve structure, provided at its upper end with a reduced screw-threaded portion 2, for engagement with an internally screwthreaded ring 3, carried by a crown or cage 4. This crown or cage is provided with spaced longitudinal openings 5, for the free passage of the oil. 7
The reduced portion 2 is provided at its upper end with a tapered valve seat 6, for engagement with the tapered portion 7 of a disk valve 8. This disk valve is rigidly secured to a stem or shaft 9, projecting above and below the same for a substantial distance.
A transverse bar 10 is arranged within the barrel 1, beneath the disk valve 8, and
has an aperture 12, for the reception of the lower portion of the stem 9, thereby serving as guide means for this stem and disk valve.
The crown 4 is provided at its upper end with a tubular portion 18, internally screwthreaded for receiving an externally screwthreaded adjustable tubular guide 14, re-
ceiving the upper end of thestem 9. This tubular guide carries a lock nut 15, as shown. The element 14: serves to guide the upper end of the stem 9 and also limits the upw ward movement of the disk valve, by contact with a shoulder 16,- and the extent of this upward movement may be regulated by adjusting the tubular guide l.
The tubular portion 13 ciprocatory operating rod.
The valve structure herewith shown and described is of the reciprocatory type, and is employed in the well casing of an oil well, in the well known manner, that is to say the valve structure is reciprocated. I may also is externally threaded at 17, for connection with a re-- embody my invention in a standing valve structure, wherein the barrel -or body portion of the device is stationary.
In view of theforegoing description it is thought that the invention will be fully understood without further explanation.
It is to be understood that the formof my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claim.
vHaving thus describ d my invention, I claim A valve structure of the character described, comprising a barrel provided at its upper end with a tapered valve seat, a cage secured to the upper end of the barrel and provided at its upper end with an internally screw-threaded portion, an adjustable tubular guide engaging within the internally screw-threaded portion, a clamping nut carried by the adjustable tubular guide, a disk valve engaging the valve seat, a stern secured to the disk valve and extending above and below the same with the upper end of the stem projecting into the tubular guide,
and a transverse bar arranged within the barrel and apertured for receiving the lower end of the stem.
' JOHN PHILIP MoEVOY.
